lM PROVEMENT IN MACHINES FOR FULLING AND SCOURING CLOTH.

Specification forming part of Letters Patent No. 186,363, dated January 16, 1877; application filed i December 18, 1876.

To all whom it may concern:

u Be it-knownthat I, ROBERT D. NEs rTH,

of J ohnstown, Gambria county, Pennsylvania, have Invented certain Improvements in Maf which I will now proceed to describe, reference being had to the accompanying drawing, in whicht Figure l is a vertical sectional view of a scouring-tub with my improvement; andFig. 2, a plan view, partly in section.

A represents one of a number of scouringtubs arranged side by side in a suitable apartment, each tub consisting of a casing, in which is arranged a pair of pressure-rollers, B, the scouring of the fabric being eii'ected by first coating it with a solution having an affinity for the oil in thefabric, and then passing it between these rolls. i

The usual method of applying the scouring solution to the fabric is to pour it in upon the same through the door D from a bucket or other receptacle in which it has been carried Not only is this plan objectionable onaccount of its uncleanliness and the expense of labor and time which 1t incurs, but also because the solution, when applied in this way, impregnates the fabric unevenly, and interferes with the proper scouring of the same.

To overcome these objections I arrange at one end of the row of scouring-tubs, or at some other suitable point, an injector, E, consisting of a spherical casing, having an internal nozzle, b, and two inlets', d and d, one at each side, these inlets communicating through valved pipes F and F, the former with a reservoir containing the scouring solution, and the latter with areservoir of water. The injector is supplied with steam from any adjacent generator, the steam being conveyed to the nozzle 1) through a valved pipe, f, and the outlet-tube e of the injector is connected toa distributing-pipe, G, which extends along the entire row of scouring-tubs, and is provided with a number of branches, J, one over each tub, each of these branches being furnished with a stop-valve, i. In the present instance each of the branches J communicates at the I end with two nozzles, P, which extend downward through the cover of the scouring-tub, and terminate preferably directly over the fabric at a point before the latter reaches the into any tub which it is not desired to use be- 7 ing prevented by closing the valve '5 of the branch J corresponding with that tub. The solution passes from the nozzles P, and falls in an even and steady stream onto the fabric just before it passes between the rolls, so that every portion of the fabric is evenly and thoroughly impregnated with the solution, and the scouring operation thereby facilitated and rendered more effective. After a sufficient quantity of the solution has been injected,its flow is stopped by closing the valve in the pipe F, and the passage of the cloth between i the rolls is continued until the grease has been thoroughly removed therefrom by the action of the solution. The valve in the pipe F is then opened, so that a stream of water, warmed by its admixture with the steam, is thrown onto the cloth, in order to wash away the suds and oily matter extracted during the previous operation, the scouring process being concluded by closing the steam-jet, and allowing the cold water underits normal pressure to flow, through the pipe G, branches J, and nozzles 1?, onto the clothl It will be evident that the device above described may be applied to machines for fulling as well as for scouring cloth, by connecting the pipe F to a reservoir containing fulling instead .of scouring solution, the advanrapidity and effectiveness of operation, being equally prominent in either case.

I claim as my invention- 1. The combination of a falling or scouring tub with a nozzle 0r nozzles, P, and devices, substantially as described, whereby a steady and even flow of the fulling 0r scouring solution through said nozzle or nozzles is insured, as set forth.

2. The combination of the injector E, its nozzle b, and inlets d and d, and the fulling substantially as described.

3. The combination of the falling or scouring tubs A and injector E with the distributing-pipe G, valved branches J, and their nozzles P, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses;

ROBERT D. NESMITH.
